Give ToList preference for WhenAny

[DickBaker]

Docs suggest using LINQ extension method ToArray() to initiate execution. Whilst this is true and may be the right style for WhenAll() coding, I favour use of ToList() instead as this is more appropriate for the WhenAny() style [handy to handle completions as they arise] as often you have to .Remove() that completed Task from the in-progress list (s.t. all work is only complete when that list is empty). Would be good to explain & contrast imho. Thanks.
